It says on Wikipedia that Alkhema was once defeated by Hawkeye when Hawkeye used an anti-metal arrow on her that was able to disintegrate her adamantium body.  Is this true?  Why isnt there a page for such a powerful weapon?  Why hasn't it been used since??  

Wikipedia isn't fool-proof.  The fact that people can edit whatever they want whenever they want is a big problem with that site to me.  It seems like the creators wanted to cover their a$$e$ and have a ready scapegoat at all times.  Whenever I find "odd" or "inaccurate sounding" information about comics happenings, I usually look here first. 
 
I don't follow the Hawkeye (or Avengers) but I would go with someone just really wanted their underdog to come out on top and had an idea and threw it there to gain public support or win a bet at school or something.

" Anti-metal is an extremely rare and pecious metal found only in the savage land and maybe wakanda. im geussing Hawkeye just couldnt get anymore. "

" @Violet-Eyed Dragon: i  would disagree. what if a villain got ahold of it during a fight or something that could put the entire planet in danger "

" @Violet-Eyed Dragon: maybe either way its still dangerous. "
